Crazy Legs

I have a Series 73 Carburetor. It started acting up at the field today. Turns out that the three O-Rings on the Mixture Control Valve got hard and they are not keeping the Mixture Control Valve in one place anymore; the valve can spin too freely with vibration and so it moved away from its proper setting. The Part Number for the Mixture Control Valve is 26281601. Can someone tell me if I can replace these O-Rings (see attached photos). If you know where I can get them please let me know. Thank you. From Mike D'Amico, West Melbourne, Florida.

Update: I found a new, unopened Mixture Control Valve on eBay using the Part Number in the Carburetor Exploded Diagram, so I think I'm good to go.

Hi,

Have you tried Amazon? Like here you can buy an o ring kit and choose the one that fits best.

As an example here:

Remove the o-rings from the valve screw and measure them, then go to theoringstore.com and order a handful. It’ll cost you a few bucks.
